of. the turntable 2 is a frame 7 which supports the operating parts of the brake. Within a socket in the frame 7 is mounted a plunger 8 which is pressed toward the turntable by means of a spring 8 engaging one end of the plunger and abutting against the end of the socket. 'The opposite end of the plunger carries a brake shoe 9 preferably oi felt, leather or the like.

Within the trance and communicating with the socket is a slot 16. A knob 11 carried by the plunger projects through this slot and is limited in its movements by the slot. The plunger is provided with a circumi-erential groove 12 for a purpose to be hereinafter described Carried on an extension of the frame? is a pair of electro-magnets 12, 12 605p crating with the magnets is an armature 13 I whlch is mounted on an arm 14 pivoted at 15 and projecting through a recess in the frame 7 and passing under the plunger 8.

The armature 13 may be retracted from the poles of the magnets by gravity but ll prefer to make use of a light spring 16 for that purpose.

Resting on the record disk and moving therewith is placed a contact arm for cornpleting the circuit through the magnets to set the brake. This contact comprises a flat plate 17 having one end beveled and the other end slotted. The plate is slidably mounted in a Weighted turret 18 which is provided with a recess 19 for that purpose. The recess provided with interned flanges 20 to retein the plate 17 in place when the turret is removed from the disk, A. spring 21 between the roof of the recess and the flanges serves to retain the plate 1'? in the desired position. The slot in the plate plays over a collar depending from tie roof of the turret and the plate is provided With a" knob 22 by means of which it may be ad justed in the turret. 'lhe turret is erforated through its center and the opening is designed to make a relatively close fit with that portion of the motor shaft which projects above the record disk. The plate 17 is held in place by the Weight otthe turret and its engagement with the shatt: Below the turntable the motor shaft is provided "with a ring 23 and engaging this ring is a brush 9A in the circuit 25 which includes a battery 26, magnets 12, 12, circuit-breaker finger 27 carried .cuit. through the magnet.

28, frame 7, tone arm e, needle 6, plate 17, turret l8, shaft l and ring 23.

The operation of so much of my improved device-as has been described above is as follows: The turret is placed over the end of the motor shaft and on top of the record with the beveled end of the plate 17 .restin adjacent to the inner end of the record groove. The plunger 8 is moved back against its spring and the armature arm will, by means of the spring 16, be held in engagement with the groove 12 in the plunger and the brakeshoe will be held away from the turn table. The motor on being started will rotate the turntable and t e engagement of the needle with the record groove feed it toward the center of the dish and the inner end of the record groove. When the metallic needle reaches the end of the record contact with the plate 17 and close the cirspring will move the plunger and apply the brake. When the plunger has nearly reached its extreme movement to apply the brake, a on the plunger will strike against an inclined arm on a circuit breaker 28 pivoted at 29 to an insulating block on (the frame, and move the circuit breaker from its contact with the frame thereby breaking the circuit after the brake has been applied and prevent the running down of-the battery. The insulating block carries a stop 30 to prevent excessive movement of the contact breaker. When the brake shoe is released from contact with the turntable the finger 27 will be moved to the right and the domes of this mtent may be obtained for five cents each,

needle of wood, glass or any other noirccn ducting material, the plate 17 may be pro vided with a finger 31 which will Contact with a metallic part of thespeaker.

In accordance with the provisions of the patent statutes, I have ciple of my invention together with the apparatus which I now consider to represent the best embodiment thereof, but I desire apparatus shown is merely illustrative and that the in vention can be carried out in other Ways.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is, as follows:

brake comprising a frame, a spring actuated plunger carried in the frame, a magnet, means controlled by the magnet for holding the plunger against the spring pressure, a circuit for the magnet, a circuit breaker on the plunger for moving the circuit breaker to break the circuit after the magnet has been energized and the plunger has been released, and a stop carried by the frame to limit the movement of the circuit breaker.
